Establishing Ground Communications Flashcards
Where are frequency coverage and broadcast requirements found?
- PCA
- DAH
- ERSA
- Published En Route and Visual Navigation Charts
On initial contact with Air Traffic Control a pilot must commence the transmission with the call sign of _________________ followed by the ________________.
- the unit being addressed
- aircraft call sign
How will ATC respond to a pilot’s initial contact to establish two way comms?
The ATS unit will respond using the pilot’s call sign followed by their call sign.
Provide an example of initial contact between pilot and ATC
Pilot: MELBOURNE CENTRE QANTAS ONE
ATC: QANTAS ONE MELBOURNE CENTRE
After any frequency change, pilots must advise what?
- last assigned level
- if not maintaining last assigned level, the level maintaining or last vacated level
e.g. MELBOURNE CENTRE (CALLSIGN) CLEARED FLIGHT LEVEL TWO ONE ZERO, MAINTAINING FLIGHT LEVEL THREE ONE ZERO
When not maintaining level flight, what must pilots include in their initial contact transmission?
ON CLIMB or ON DESCENT as appropriate.
MELBOURNE CENTRE AMBULANCE FIFTEEN ON CLIMB FLIGHT LEVEL ONE FIVE ZERO LEFT SEVEN THOUSAND FIVE HUNDRED FEET
When must a pilot include the last vacated level in an initial contact transmission?
When not in receipt of a surveillance service
What is a station holding primary guard responsible for?
- nomination of suitable primary and secondary frequencies;
- receipt of all position reports;
- handling of messages essential to the safe conduct of the flight;
- provision of flight information to aircraft operating outside controlled airspace but within its FIA;
- provision of a flight information service to aircraft operating in foreign FIRs/UIRs when coordination with the responsible ATS unit is not forthcoming; and
- actions required in case of communications failure.
Where does the term primary guard apply?
Where air-ground communication is limited to HF frequencies that are shared and managed by more than one station
In what regions may assuming primary guard occur?
In the Oceanic Control Area (OCA) where Flightwatch International (Brisbane HF) is the regular network station for communications using:
1. SP6 - South Pacific 6
2. INO1 - Indian Ocean 1
3. SEA3 - South East Asia 3
Primary guard should be assumed when?
- an aircraft departs from an aerodrome and establishes communications;
- primary guard is transferred by another unit;
- an aircraft establishes communications and requests primary guard be accepted; or
- an aircraft enters Australian-administered airspace without prior coordination.
When should primary guard be transferred?
- at an FIR boundary;
- when you cannot maintain satisfactory communications; or
- when an aircraft requests a change of primary guard.
When does responsibility for primary guard of an aircraft cease?
- is known to have landed at an aerodrome;
- is transferred to another station;
- transfers to an area or aerodrome control frequency; or
- is operating outside Australian-administered airspace and the regular station is no longer in communication with the aircraft.
When relayed by third parties, messages between controllers and pilots should be relayed ___________ for __________
Word for word
Define primary guard
The process whereby responsibility for HF
communications with a particular aircraft when using an International HF network, which has more than one operator, is regulated.
